APPARATUS FOR HANDLING OIL FOR FUEL.

SPECIFICATION forming part of Letters Eatent No. 537,584, dated April.16, 1895.

Application filed April 12, 1893| Serial N01 470,066- (No model.)

T0 on whom it may concern.-

Be it known that I, WALTER S. ROCKWELL, of New York, in the. county ofNew York and State of New York, have invented certain new and usefulImprovements in Apparatus for Handling Oil for Fuel; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in apparatus for handling oil forfuel purposes, the object being to provide means for regulating thepressure to any desired amount and when set at a certain predeterminedpoint to hold it there without fluctuation thereby producing a perfectlysteady fire.

A further object is to provide means for heating the oil to acomparatively high temperature without the possibility of evaporationand loss thereby, and rendering it ready for quick combustion.

A further object is to provide for cleaning and separating the oil fromsediment, water or other foreign matter, thereby fitting it for deliveryto the fire through a very small open ing without choking.

pearing in section.

A still further object is to carry a small quantity of oil underpressure with the above named advantages and to remove it from thepremises entirely and quickly when desirable to do so thereby making ita safe and reliable fuel.

With these ends in view my invention consists in a tank orstoragechamber or connected chambers in which a supply of air, oil

and Water is maintained under constant and uniform pressure, the three.elements being confined in a -single chamber or in connected chamberswhereby the pressure upon the oil is kept uniform at all times.

The invention, further consists in certain novel features ofconstruction and combinations of parts which will be hereinafterdescribed and pointed out in the claims. I

In the accompanying drawings, Figure 1 is a view in elevation showingthe arrangement of the pipes, the tank or storage chamber ap- Fig. 2 isa view in end elevation. Fig. 3 is an enlarged view of the tank; andFig. 4 is a bottom plan of the tank.

A represents the tank or storage chamber, of which I have shown only onethough three could be used to advantage provided they are suitablyconnected together. This tank is made in the usual manner, of boileriron with the heads riveted thereto so that the entire tank or chamberis closed except at points where the pipes enter the bottom.

Two pumps B B are secured on the support, which also holds the tank, andat opposite ends thereof, the two being provided so that in case onegets out of order at any time the other will do the work without causingany needless delay. A suction pipe 1 leads from the supply pipe 2 toeach pump and a discharge pipe 3 extends from one pump to the other.This discharge pipe 3 has leading from it in a downward direction a pipe4. Pipe 4. continues on down, preferably having the elbow 5' formedtherein, and thence it connects at its lower end with thesupply pipe 2forming a by-pass for the oil to flow through from the pump after thepressure has reached a certain predetermined point in the tank orstorage chamber, as will be explained more fully hereinafter. At-a pointabove the elbow 5 a branch pipe 6 leads into the bottom of the tank asshown in Fig. 2. In these several pipes the necessary valves arelocated. as follows:

In pipe 3 there are two valves 7, 7, one between the point where pipe 4joins pipe 3 and each pump. As only one pump is used at a time of coursethe valve adjacent to the idle pump is closed and both maybe closed whenboth pumps are stopped. In the elbow 5 there is another valve, apressure or regulator valve 8. This latter valve is turned to regulatethe pressure under which the oil shall be maintained in the tank orstorage chamber A. Still another valve, a check valve 9, is located inpipe 6 this being provided to prevent the oil from flowing back out ofthe tank, once having been pumped into the latter.

A water pipe 10 connected at one end with a water supply under pressureis preferably connected at the other end with the inner end of pipe 6 asthe most convenient place for such connection and in this pipe 10 avalve 11 is provided for regulating the How of water therein or forcutting it off entirely as the case may be. It is also provided with acheck valve to prevent the water from flowing out of the tank afterhaving onceentered thelatter. This pipe may be used as a source ofpressure upon the oil in event of both pumps being stopped for anyreason, and when it is desired to replenish the tank with water.

A waste pipe 13 leading fromthe bottom of the tank into the sewer, isprovided for drawing off the contents should occasion require theemptying of the tank. The pipe has a valve 14 therein for opening andclosing it.

0 is the pipe whichsupplies. the: burners. Thispipe enters through thebottom ofthe tank or storage. chamber terminating atone, end near theupper end oi the tank and the other end extends to the burners. The pipeis furnished with a valve 16 by means of which the supply of oilto'the.burners may be cut off.

In order to heat the oil as economically as possible the exhauststeampipe 17 is'carried alongside the supply pipe2 in close proximity theretoso that by the time the oil reaches the tank it has the desiredtemperature.

Other accessory features such as valves 19, 19, in the suction pipes 1,1, valve 20 in the supply pipe, steam gage 21, pressure gage-22,thermometer 23, and automatic. self closing gage cocks 24 are provided,but. as. they are common to this variety of apparatus they do notrequire further description here.

In operation valve 11 is opened in water pipe 10 and the desiredquantity of water is allowed to flow into the tank. The engineer needonly look at the gage 24: to ascertain when enough water has entered thetank. When the water level has reached the desired point valve 11 isclosed. Thevalves'? and 19 on either side of the. operatingpu-mp are nowopened, the pump is started and oilis. pumped into the tank and as it isdischarged into the bottom of the tank it passes upward through thewater, assuming a position over the water and between the water andairspace, owing to its specific gravity being greater than the one andless than the other. continues until the elastic or compressible medium,as air for instanceatthe top is compressed to the degree required tocreate the desired pressure, the. pressure being regulated by valve 8which is set. at the proper point beyond which the. valve opens and al--lows the oil to flow through the by pass and out into the supply pipe. 2again so that should the consumption at the fires be destopping orvarying the speed of the pumpin the least, the valve 8 willautomatically relieve the pressure and permit the oil to flow outthrough the by'-pass just as fast as it is I contain water and {LIIelastic 01' 00111 I'GSSldischarged from the pump, and on the other handthe moment the consumption begins again valve 8 automatically readjustsitself and in this way the same pressure is maintained. Of course it isunderstood that the pressure may be increased at any time by screwingthe valve 8 in, or it may be reduced by opening the valve wider asdesired.

It will be observed from the drawings (Fig. 1) that the height of thepipe 0 is such that the level of the oil is never much above the openend of the pipe, but this level is kept uniform when the apparatus is inopera tion, that is to say, so long as the pump is supplying: oil or inoperation under water pressure, and this provision is made so that incase of leakage, as for instance the result of carelessly leavinga-burner valveopen over night, at. most only a comparatively smallquantity of oilcould leakout before thelevel of the oil would drop belowthe open end of pipe. 0.

Thus, to. recapitulate, it will be seen that I am enabled to regulatethe pressure upon the oiland when set at a certain pressure to hold itthere without fluctuation, thereby producing'a perfectly steady fire. Iam enabled to heat the; oil to a. comparatively high tem- .pera-turewithout the possibility of evaporation and loss thereby, expanding it sothat as itpasses upward through the water it is entirely freed fromforeign mattersuch as sediment, water, &c., and rendered ready for quickcombustion through a very small opening withoutchoking; and tinallyI amenabled to. carry a. small quantity of oil under pressure; with theabove named advantages, and

to remove it entirely from the premises. by

,simply opening the valve let at any time and permitting the oil andwater to flow out.

Having fully described my invention, What i I claim as new, and desiretosecure by Letters i Patent, is-

l. The combination with a tank adapted to receive and hold oil, waterand an elastic, or compressible medium, and means for creating apressure greater than the atmospheric press- I ure-upon the oil andwater contained in the tank, of a pipe leading from the tank to theburners for supplying oil to the latter, substantially asset forth.

2. The combination with a tank adapted to ble mediulmand pump forcreatingapressure upon the water and oilgreater than the atmosphericpressure, of a pipe leading from the tank to the place where the oil isto be used,

a pipe leading from the pump into the tank, a by-pass leading from thispipe, and a pressure valve in. the by-pass, substantially as set .forth.creased or stopped at any moment without 3. The combination with. atankadapted to containoil, water and an elastic or com pressible medium, ofa discharge pipe, a pump, oil pipes leading to and from the pump and awater pipe leading from a water supply un- IIO tier pressure into thetank, substantially as set forth.

4. The combination with a tank adapted to contain air, oil and water,regulating gage and pressure gage, of a pump, for supplying 'oil to thetank, and discharge pipe for oonducting the oil from the tank to theburners, substanstially as set forth.
